To all whom it may concern.-

' Be it known that I, JOHN .F. APPLEBY, of I Iarvey,"Illinois,'haveinvented certain new and useful Improvements in Knotting Mech anis'lnfor Self-Binding. Harvesters, of which the following is a specification.

My invention relates to certain features of improvements in the knottingmechanism of a self-binding harvester, and more particularly to animproved cord carrier and holder and to a novel arrangement of thecord-latch with reference to the slot of thefbreastplate. The object ofmy invention is to provide a cord-holder of very simple construction,having few parts not likely to get out of order, which will effectacertain holding and delivery of the cord to the cord-hook and whichwill present the cord to the severing-knife and deliver the. cut endsout of the cordholder without liabilityof clogging.

My cord-holder is also of such construction that the two strands of thecord are separated and kept separated during the period: of rotation ofthe holder, whereby any entanglement of the strands or interference ofone with the other is prevented. v 1

In the accompanying drawings,- Figure 1 is a perspective View ofthe'knotterehead and breastplate, the'needle withdrawn; and Fig. 1 is asimilar view-showing the needle at the forward limit of its stroke. Fig.2 is an elevation of the binder-head, showing also the deck and packermechanism. 'Fig. 3 is a plan view of the breastplate and a latch forclosing the cord-slot therein. Figs. 4, 5, and 6 are similar views ofthe breastplate, showing the latch, knotter-hook, and cordholder indifferent positions, some of the other parts in section. Fig. 7 is anenlarged sectionallplan showing the cord-holder and a grooved shoecooperating therewith partly broken away. Fig. 8 shows the knotter-hookand knot.

My improvements may be readily applied to any of the leading types ofself-binding harvesters, and the mechanism which I have shown-isillustrative" merely so far as said parts are not. hereinafterparticularly described andblaimed.

I will merely designate parts whose construction is well known byreference-numerals, but without particular description.

- of the cord itself.

10:.represent the breastplate, having a cord-slot 11 of outlinessubstantially such as heretofore employed, the slot being of irreg-'ular.-for1n and-carried around a projecting shoulder 12, which serves,-in conjunction with a latch 13, to retain the cord and prevent itspassing into the forward part of the slot while the gavel is forming.The latch 13 is pivoted at one side of the slot and substantially inline with the shoulder 12 or opposite the extremity thereof. against theforward orleading-in side of the shoulder 12 by the spring 14, and theend of said latch lies in a plane substantially at right angles to theforward face of the shoulder '12 and parallel to the path of the needle15. When theneedle advances to carry a strand of the cord to thecord-holder, as

shown in Figs. 1 and et the cord will be prevented from passing into theforward portion of the slot byv the end of the latch and the two strandsof the cord'will be separated, as shown in Fig. 4, and 'will lie overthe point of the hook 16. The latter then begins its revolution,carrying both strands of thecord, as shownin Fig. 5 Th'epoint of thehook moving ina circularpathhas a tendency,

its construction and automatic in its operation, it will be observed, isnot controlled mechanically by a moving part of the binder mechanism, asusual, but is normallyheld in position to close the, slot by a simplespring,

The latchis normally heldand is lifted to uncover the slot by the actionThe latch is so arranged that the pull of the cord is endwise upon thelatch or in line with its pivot while the cord is being tightened aroundthe bundle, and after the knotter-hook engages the cord the strain iseccentric to the pivot of the latch, so that the latter is lifted andthe cord passes beneath. I

My cord-holder mechanism is also of very simple construction. Thecord-holder shaft is marked 18, and it is driven intermittently in awell-known manner, the gearing being so timed that the cord-holder shaftperforms a half-revolution during the tying of each bundle. 011 thelower end of the cord-holder shaft is fixedly mounted a flat disk 19,preferably of sheet-steel, which may be very thin, say on e-eighth of aninch. This plate is shown in full size in Fig. 7, and it is arranged ina plane at right angles to its axis of revolution. I11 contour itsperiphery presents two eccentric segments 20 and 21, and near the baseor narrow portion of each of said segments and in advance of the highpoint of the other of said segments are provided the oifstanding prongs,teeth, or projections 22 23. These teeth serve to engage a strand of thecord and to carry or move it toward the knotter-hook. Vorking inconjunction with the disk 19 is a shoe 24, which is pivotally mounted,as upon the stud 25, and backed up by a fiat spring 26. The shoe has acurved inner edge arranged concentric to shaft 18 and a groove 27 in itscurved edge. Said groove is only slightly wider transversely than thethickness of the disk, as the cord does not necessarily enter thegroove, but is impinged against the edges of the shoe at the opening ormouth of the groove by the edge of the disk, the forward movement of thecord being effected by the prong or tooth.

In order to separate the strands of the cord and to guide the strandcarried by the needle, I employ the upstanding cord-deflecting plates 2820. For convenience of construction said plates may be formed integrallywith a plate or strip of sheet metal 30, apertured for the passage ofthe shaft 18 and secured to the disk 19. These plates are notched ontheir front edges, as shown at 31, and their outer sides form an acuteangle with the disk 19. The edges of saidplates are inclined preferablyon a curved line. As the needle advances, carrying the cord across thecordholder, the strand carried by the needle will be deflected towardthe axis of the holder by the edge of the plate and thereby separatedfrom the strand which is engaged by the prong of the disk. As the needlereturns, the strand of the cord carried thereby will be deflected by theinclined edge of the deflecting-plate away from the center of the diskand into the notch 32, between the prong and the high point or shoulderof the adjacent segment, and the continued backward movement of theneedle will then draw the strands of the cord back over and around saidprong, as clearly seen in Fig. 7.

A cord-severing knife 33 is secured on the sleeve-bearing of shaft 18,the knife being positioned back of the knotter-hook. After the knot istied the strand, which is then lying across the cord-holder and throughthe point of the needle, as seen in Fig. 6, is carried by the notchedend 31 of one of the plates 28 or 29 into contact with the knife, andthe cord is severed. By the time the severing of the cord is eifectedone of the ends thus severed is engaged by the prong or tooth of thedisk and carried into contact with the grooved shoe. Thus it will beseen that the strands of the cord which pass across the cord-holder arekept separated from each other, so that their entanglement orinterference is entirely prevented. Further, it will be seen that theneedle carries the strand of the cord below the plane of thecord-carrying disk, so that said strand crosses the plane of the disk inposition to be engaged by the tooth at the next actuation of the disk,the tooth lying in such a position that it engages the cord from theupper side and the return of the needle carrying the strand of the cordover and around the tooth, as previously described. It is also seen thatbut one strand of the cord is severed and that the severed end isrelatively short. The points 34; of the disk 19 serve as clearers toinsure the clearing of the groove, and the eccentric surface of thesegments 2O 21 serves also to assist in deflecting the cord into thenotches 32.

I claim 1. A cord-holder comprising in combination a disk havingperipheral prongs or teeth extending in the plane of the body of thedisk, a shoe having a portion thereof curved to conform to the disk andarranged adjacent thereto and a groove in the plane of said disk andinto which said prongs may enter and said disk having upon its surfaceupstanding deflecting-plates, substantially as described.

2. A cord-holder disk having outstanding pins or prongs at oppositepoints of its periphery and upstanding plates on opposite sides of itsaxis, said plates having inclined edges arranged to deflect the strandof the cord carried by the needle, substantially as described.

3. A cord-holder comprising in combination a rotatable disk having itsperiphery composed of two eccentric segments each terminating in ashoulder, an outstanding prong or tooth projecting from each of saidsegments near its base, a cooperating shoe having a curved grooved edgeadjacent to the edge of the disk, the prongs serving to carry the cordto the knotter and the shoulders serving to clear the groove,substantially as described.

4:. A cord-holder comprising in combination a rotatable disk having pinsor prongs projecting from its edge in the plane of its body, a groovedshoe arranged adjacent to the edge of the disk, said disk havingupstanding defleeting-plates on opposite sides of its axis, said plateshaving notched ends, and a stationary knife to which the cord is carriedby the notched ends of the plates, substantially as described.

5. The combination with a slotted breastplate having a shoulderprojecting into the slot of a spring-controlled latch pivoted oppositethe shoulder and a cord-knotter hook rotatably mounted in such relationto the latch that by the rotation of the hook the cord 10 located thatthe strain of the cord against the end of the latch is radial to thepivot While the knotter-hook is stationary and said latch being adaptedto be opened by the upward and outward strain of the cord during theroration of the hook, substantiallyas described. 15
